METHOD OF MOUNTING AND PRESERVING PHOTOGRAPHIC PROOFS AND COPIES.

SPECIFICATION forming part of Letters Patent No. O0,031, dated March 19, 1889.

Application filei September 13, 1887.

$0 aZZ whom it may concern:

Be it known that I, DANIEL K. ZUHWALT, acitizen of the United States, residing at Visalia, in the county of Tulare and State of California, have invented certain new and useful Improvements in the Method of Mounting and Preserving Photographic Proofs and Copies, of which the following is a specification.

My invention relates to an improved method of mounting and preserving photographic proofs or copies in such a manner as to neutralize the tendency of the sheets to cockle or curl inward toward the albuminized or printed sides. The method of mounting which I employ can be utilized in mounting and preserving such prints from whatever subject they may be made and whether they are designed ultimately to be collected and bound in book form or not; but the invention is especially adapted for use in the preservation of facsimile copies of records, deeds, and other legal instruments in convenient form for reference, as a substitute for the modes or methods of copying the same'by hand, as heretofore ordinarily employed in public offices.

My invention consists in mounting and preserving such proofs or copies by placing two of them back to back without any intervening card or sheet and permanently uniting them by some suitable cement, so that the tendency of the sheets to cockle or curl inward toward the albuminized or printed sides will be neutralized; and when desirable the sheets so mounted are collected, arranged in proper order, and bound into book form. The advantages of this method of mounting in cconomizing space, reducing the weight and bulk, and at the same time preventing the cockling and curling as effectually as though the sheets were mounted on card in the usual way, may be utilized without the subsequent binding in book form, as the character of the subject of the photograph may dictate; but in copying deeds or other instruments for reeord the mounting will preferably be followed by arranging and binding in book form the sheets so mounted.

I will describe the details of the invention as applied to deeds and other instruments for record; but it will be understood that the invention is, as already stated, applicable to Serial No. 249,606. (No specimens.)

photographic prints or sheets of any subject, whether written or printed documents, landscapes, buildings, portraits, and the like. The deed or other instrument presented for record is photographed of reduced size, and from the negative obtained, copies are printed in the usual way upon albuminized paper.

A print is obtained of each page of the document in this manner, and then every two prints or copies are firmly pasted back to back to form a single leaf or sheet. As many leaves or sheets are formed in this manner as it requires to produce all the pages or sides of the instrument, and all the copies thus prepared of instruments filed for record from time to time being made of uniform size, I bind the sheets together in suitable order and number to form a volume of convenient bulk. By placing and securing two leaves or sheets of the albuminized paper back to back I am enabled to dispense with card-board mounts, heretofore required, as the tendency of one sheet to curl up is counteracted bythe same tendency in the other sheet, and a thin leaf or sheet that will remain smooth and flat is obtained. In consequence of this it is practicable to bind a considerable number of such leaves in book form, in this manner producing fac-simile copies on a reduced scale of a number of instruments and documents presented for record arranged in suitable order and bound together to form a book of convenient size. Such a volume will be much smaller than the large and bulky recordfolios heretofore used, and, aside from the reduction in cost of the book and the time and expense of copying the instruments, the copies will be found to possess several advantages over manuscript copies. All the characteristics of the original papers are given in the records, with the changes, interlineations, and erasures, and the record cannot be altered or tampered with, as the photographic prints will plainly show the slightest attempt at alteration and the paper will not stand erasures. All signatures on the original instrument will be given in fac-simile in the record, and this will aiford at all times thereafter proof of the genuineness of the instrument.

This method of producing and preparing public records is applicable also to preparing abstracts of title in a complete form. In such ease duplicates of the deeds or instruments in the chain of title are prepared either by printing from the photographic negatives previously taken in making up the original reeords or by taking photographic copies from the reeords themselves of convenient size, and these photographic copies are then mounted in Slllllilldtl order, two sheets back to back, and linally l )ound together. Such an abstract will furnish a tae-simile copy of each deed, transfer, and other instrument relating to the title, and besides, being generallyless expensire to produce, an be completed in mueh less time than can be done by hand.

I [a-ving thus fully described my inventioin what I claim, and desire to soon re by Letters Patent, is i l. The herein-deseribed improvement in the art of mounting photographic prools or prints ol' deeds or other subjeets, \vhieh eonand. other documents, wh'ieh consists in Iii-st plaein and permanei'itly uniting two of said copies back to back, and then collecting and binding a n umber ot the same into book form, substantially as and for the purpose speeilied.

In testimony that I elaim the foregoing l have hereunto set my hand and seal.
